Movement is the German manual-wind Lange in-house caliber L093.1 with 21 jewels (with 3 screwed gold chatons), 21,600 vph and a power reserve of 72 hours. It is decorated and assembled by hand; precision-adjusted to five positions; made of untreated German silver; balance cock engraved by hand, featuring a lever escapement, a shock-resistant screw balance; balance spring manufactured in-house and a precision beat-adjustment system with lateral set screw and whiplash spring.

For these new models, the dial has baton-style hour markers in solid gold, slightly extended and moved closer to the bezel. This gives the argenté-colored solid-silver dial extra prominence. Hands are rhodiumed gold.

It comes on a black or reddish-brown hand-stitched alligator leather strap with an 18kt white or rose gold buckle.
